What Are Examples of Electrical Devices?

Some examples of electrical devices include light bulbs, vacuums, toasters and older technologies such as the electric telegraph and batteries. Electrical devices are defined as devices that use or generate electricity and transform it into another form of energy, such as motion, heat or light. The transformations created by electrical devices are simple in nature and typically serve to do only one action.

Electrical devices are in a different category than electronic devices. An electronic device, such as a modern cell phone or mp3 player, uses complex manipulation of electricity to perform additional actions by utilizing the electronic current to add audio or visual information.

Electrical devices predate the creation of the electronics field of study by approximately 100 years, with the first electrical batteries being invented in 1800 by Alessandro Volta. Some archaeological evidence has also found that an electrical battery was in use in the ancient Parthian Empire in the second century B.C. Other early electrical devices include the telegraph, which was invented in the 1830s. The telegraph later used Morse code, which was invented by Samuel Morse to allow for nearly instantaneous communication over long distances.

Modern electrical devices often have electronic components in them, such as a temperature control feature on a toaster.
